Losi Xcelorin Help

[PaulL]

Hi, i'm having trouble setting up my Losi Xcelorin Sensored Speedo.

I'm running a B4 on mixed surfaces (indoor and out) and can't get the speedo to run properly. It cogs massively on initial acceleration and coming out of corners. The only way i've managed to stop it so far is to under gear a lot (at least 3 teeth from recommeded)

I've got 6.5 and 10.5 and the same happens for both, once undergeared it runs flawlessly, but very low top end speed because of gearing.

Does anyone use one of these? And is there a good way to set it up to stop this?

Thanks.
